IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part of Letters Patent No. 160,105, dated February23, 1875; application filed November 9, 1874.

To all whom it may concern Be it known that I, WILLIAM M. KoPPEs, ofSeville, in the county of Medina and State of Ohio, have inventedcertain new and useful Improvements in Grain- Separators; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in grain-separators. It consists inupwardlyinclined bearing-rods attached to the frame of the separator,and which support the sievebox, and which are so arranged as to impartto the vibrations of said sieve-box an undulatory motion, as hereinafterfully explained.

In the drawings, Figure 1 is a rear end view, Fig. 2 a verticallongitudinal sectional view, and Fig. 3 a horizontal sectional view, ofthe separator with my improvements attached.

d is the sieve-box. It is constructed in two parts, d1 d2. The upperpart or shaker, d1, is supported by and vibrates on the bearingrodshereinafter described. Z3 are the upwardly-inclined bearing-rods. Theirouter ends are fastened to the frame or side of the separator. Theyincline upward from their fastenings on the frame, and pass throughmortises formed in the side slats or bars of the sieve-box. They supportthe shaker d1 in my separator, (but would support the entire sieve-boxwhen constructed with the several of the grain from the chaff. The underpart d2 of the sieve-box is supported by and vibrates on the horizontalrods d4, the latter being attached to the frame of the separator, and soarranged as to give a proper inclination to the box to secure thedelivery of the grain into the discharge-trough. The two parts dl d2 areconnected to cranks on the axle or shaft d7 by means of the shaking-rodsd6 d5. The shaft 617 is geared to the axle of4 the fan, the latter beingoperated by suitable pulleys and belts connecting with the operatingmachinery of the separator. The cranks on the shaft t7 are so arrangedthat they communicate a reverse reciprocal movement to the two parts d1d2 of the sieve-box.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

The upwardly -inclined bearin g rods d3 in combination with the shakerd1, for the purpose set forth.

In testimony that I claim the foregoing as my own invention I aftix mysignature in presence of two witnesses.
